Conway coefficient sign conjecture. The conclusion of the two-component obstruction holds whenever $L\in\mathcal{P}_0$: in general, the sign $(-1)^k$ is replaced by $(-1)^{s(k,m)}$…

For a link $L$, let $n'(L)$ denote its number of components and let $\chi(L)$ be its Euler characteristic. Define … Let $\sg(L)$ denote the signature of $L$. Signature Growth conje…
